Nintendo has released a new trailer for Pokémon X and Y showing off Charizard’s two possible mega-evolutions.

Charizard will evolve into either Mega Charizard X or Mega Charizard Y depending on which Mega Stone you give it. Give it Charizardite X and you’ll get Mega Charizard X, turning your Charizard’s body black and his flames blue. Its type will also change from a fire and flying-type Pokémon to fire and dragon-type.

Give it Charizardite Y and you’ll get Mega Charizard Y. This form increases Charizard’s special attack and gives it a new move called “Drought,” which ups the damage done by fire-type moves.

Pokémon X and Y are set to release worldwide on October 12.

Matthew Bennett finally got his big break with EGM three years ago, following years of volunteer work for various sites. An ability to go many hours without sleep and a quick wit make him ideal for his role as associate editor at EGMNOW.com. He often thinks back to the days when the very idea of this career seemed like nothing but an impossible dream. Follow him on Twitter @mattyjb89. Meet the rest of the crew.
